You have the right to defect-free goods. If your e-bike has a defect, you can fall back on legal rules. The law gives you clear claims against the seller.
Duration and rights
The statutory warranty applies to new products for two years from the date of purchase. For used goods, the period can be reduced to one year if you agree to this at the time of purchase.
For new goods: Two-year warranty.
For used goods: One year, if agreed.
During this time, you can demand the following:
Repair of the defect
Replacement delivery
Reduction of the purchase price
Withdrawal from the contract if the defect is not remedied
In the first twelve months after purchase, the seller must prove that the e-bike was in order at the time of handover. After one year, the burden of proof lies with you.
Tip: Always keep your invoice and all documents safe. This makes it easier to prove your claims.
Contact person and burden of proof
Your first point of contact is always the seller from whom you bought the e-bike. This also applies if you bought it from a dealer. In the case of private purchases, the warranty can be excluded.
You must prove that the defect was already present at the time of purchase.
In the first twelve months, the reversal of the burden of proof helps you: The seller must prove that no defect was present.
After twelve months, you must prove the defect yourself.
Written notification of defects is useful.
You should always keep invoices and receipts.
With these rules, the warranty protects you when buying and gives you security in case of problems with your e-bike.

A guarantee is a voluntary service provided by the manufacturer or retailer. You receive it in addition to the statutory warranty. Many e-bike companies offer you a guarantee to give you more security when buying. The guarantee covers certain parts and functions that the manufacturer defines itself.
Some well-known e-bike manufacturers in Germany offer you various guarantees:
Haibike: 5-year guarantee on the frame, 2 years on the motor, 6 months on the battery.
Kalkhoff: 2-year warranty on the frame, 10-year guarantee upon registration, 2 years on the motor and battery.

Conditions and scope
The guarantee only applies under certain conditions. You often have to register your e-bike to activate the guarantee. Many manufacturers require regular maintenance work. Wear parts such as brakes or tires are usually excluded. The guarantee does not cover damage caused by improper use or modifications. Theft of the e-bike is also not covered by the guarantee.
